I tried to build a simple calculator with three textFields, for data X and Y to yield result Z on the third TextField, with five Buttons for each arithmetic operator and clear button.

This is my code


i have only added Listerner to the add button.
i dont know i still keep getting errors.
Thanks

remove everything unrelated to the construction of the gui
e.g.
x.getText(dataX);
all the listener code

now you can concentrate on getting the gui to display.
when it diaplays OK, then add the listeners/functionality
 
What's that smell? I think this tiny ad may have stepped in something.
